i was explaining last night to my (younger) other half, how it was used in the jeans advert, and was i guess lee cooper trying to cash-in on punks wearing drainpipe jeans... when i was 13 it was a fashion statement that could have gotten you beaten-up by long-haired gentlemen who wore flares - and that a lot of people know the song from then, even if they don't know who it's by...
